"This update for teeworlds fixes the following issues :

  - CVE-2019-10879: An integer overflow in
    CDataFileReader::Open() could have lead to a buffer
    overflow and possibly remote code execution, because
    size-related multiplications were mishandled.
    (boo#1131729)

  - CVE-2019-10878: A failed bounds check in
    CDataFileReader::GetData() and
    CDataFileReader::ReplaceData() and related functions
    could have lead to an arbitrary free and out-of-bounds
    pointer write, possibly resulting in remote code
    execution.

  - CVE-2019-10877: An integer overflow in CMap::Load()
    could have lead to a buffer overflow, because
    multiplication of width and height were mishandled.

  - CVE-2018-18541: Connection packets could have been
    forged. There was no challenge-response involved in the
    connection build up. A remote attacker could have sent
    connection packets from a spoofed IP address and occupy
    all server slots, or even use them for a reflection
    attack using map download packets. (boo#1112910)

  - Update to version 0.7.3.1

  - Colorful gametype and level icons in the browser instead
    of grayscale.

  - Add an option to use raw mouse inputs, revert to (0.6)
    relative mode by default.

  - Demo list marker indicator.

  - Restore ingame Player and Tee menus, add a warning that
    a reconnect is needed.

  - Emotes can now be cancelled by releasing the mouse in
    the middle of the circle.

  - Improve add friend text.

  - Add a confirmation for removing a filter

  - Add a 'click a player to follow' hint

  - Also hint players which key they should press to set
    themselves ready.

  - fixed using correct array measurements when placing egg
    doodads

  - fixed demo recorder downloaded maps using the sha256
    hash

  - show correct game release version in the start menu and
    console

  - Fix platform-specific client libraries for Linux

  - advanced scoreboard with game statistics

  - joystick support (experimental!)

  - copy paste (one-way)

  - bot cosmetics (a visual difference between players and
    NPCs)

  - chat commands (type / in chat)

  - players can change skin without leaving the server
    (again)

  - live automapper and complete rules for 0.7 tilesets

  - audio toggling HUD

  - an Easter surprise...

  - new gametypes: 'last man standing' (LMS) and 'last team
    standing' (LTS). survive by your own or as a team with
    limited weaponry

  - 64 players support. official gametypes are still
    restricted to 16 players maximum but allow more
    spectators

  - new skin system. build your own skins based on a variety
    of provided parts

  - enhanced security. all communications require a
    handshake and use a token to counter spoofing and
    reflection attacks

  - new maps: ctf8, dm3, lms1. Click to discover them!

  - animated background menu map: jungle, heavens (day/night
    themes, customisable in the map editor)

  - new design for the menus: added start menus, reworked
    server browser, settings

  - customisable gametype icons (browser). make your own!

  - chat overhaul, whispers (private messages)

  - composed binds (ctrl+, shift+, alt+)

  - scoreboard remodelled, now shows kills/deaths

  - demo markers

  - master server list cache (in case the masters are
    unreachable)

  - input separated from rendering (optimisation)

  - upgrade to SDL2. support for multiple monitors,
    non-english keyboards, and more

  - broadcasts overhaul, optional colours support

  - ready system, for competitive settings

  - server difficulty setting (casual, competitive, normal),
    shown in the browser

  - spectator mode improvements: follow flags, click on
    players

  - bot flags for modified servers: indicate NPCs, can be
    filtered out in the server browser

  - sharper graphics all around (no more tileset_borderfix
    and dilate)

  - refreshed the HUD, ninja cooldown, new mouse cursor

  - mapres update (higher resolution, fixes...)"
